All that does is change some links on the site. It's not going to change what the browser URL looks like. Or perhaps I'm not understanding what you are trying to do.
Edit: BTW How would I edit the browser url on my server after changing it in the acp without screwing anything up??
Yes.
We're planning on joining our site with someone else's. He had a forum, but closed it due to inactivity, so we'll be providing the forum; he'll be providing the homepage.
It would be changed from kh-mediaflare(.)net to kh-recharged(.)net or com.
